Dear all,
I found that my freeradius service cannot be run more than 10 mins. I turned
on the debug mode, the following messages would appear before core dump
modcall: entering group authorize
modcall[authorize]: module "preprocess" returns ok
modcall[authorize]: module "suffix" returns ok
users: Matched DEFAULT at 144
modcall[authorize]: module "files" returns ok
modcall: group authorize returns ok
rad_check_password: Found Auth-Type unix
auth: type "System"
modcall: entering group authenticate
rlm_users : Time to refresh cache.
HASH: Can't open file (null): Bad address
Segmentation fault (core dumped)
I think the main point are the last three lines. Why do my freeradius server
would have core dump when it does a cache refresh (default is 10 mins). I am
the one which are using other password file and shadow file. Anyway, one
more information is, the path of the group is not the same format as
/etc/group. However, we ignore it because we find that it just read our new
shadow password. If debug mode is run, it said it stored 0 entried from the
group file.
